RAILWAY-SWITCH.

Application filed March 31, 1919.

T0 all'whom it may concern Be it known that we, STEPHEN E. SHOUP and DIoKsoN FAIRBACK, citizens of the United States of America, residents of Kansas City, in the county of Jackson, State of Missouri, and the city of St. Louis, State of Missouri, respectively, have invented certain new and useful Improvements in Railway-Switches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to means whereby the point rails of railway switches may be adjustably connected to the tie bar by which they are operated in order that the throw of the point rails may be varied according to requirement or demand. We are aware that adjustable devices of the kind to which our invention relates are not broadly new, and our invention pertains to a specific construction of adjustment device whereby greater strength and durability are obtained, with a lessened opportunity for play between the connected parts.

Figure I is a plan view of a railway track having a switch therein, including our im provement.

Fig. II is an enlarged vertical cross section taken on line IIII, Fig. I.

Fig. III is an enlarged perspective view of one of the adjustment brackets of our point rail adjusting device.

In the drawings A designates the main rails and B the point rails of a section of railway track. C is a tie bar movable transversely of the railway track in shifting the point rails to and from the main rails. The tie bar is a plain bar having vertical holes therein, suitably spaced from each other so that one of the holes may be near one of the point rails and the other near the other point rail when said point rails are in juxtaposition to the main rails to and from which they are shifted.

D designates brackets secured to the point rails B and having bolt holes therein through which bolts may extend while occupying the previously mentioned bolt holes in the tie bar C. Eachbracket D comprises Specification of Letters Patent.

Serial No. 286,329.

an arm 1 which rests upon the base flange of the point rail to which the bracket is fitted, and which is secured to the web of said point rail by bolts extending through the arm and through said web. Each bracket D also includes a horizontal U-shaped jaw or loop 2 between the upper and lower members of which the tie bar C extends. In the upper and lower members of the jaw 2 are alined bolt holes 3, 3 and 3", which receives the bolts 4 by which the brackets D are connected to the tie bar C. The bolt holes 8, 3 and 3 are arranged in series in a line which is inclined to a line extending longitudinally of the point rail to which the bracket D is attached. The tie bar may be connected to the brackets D by placing the bolts 4 in any of the holes 3, 3 and 3", and the point rails will be adjusted accordingly relative to the main rails; for example, if the connection of the tie bar to a bracket D is made by placing a bolt 4 in the bolt holes 3, which are nearest the point rail to which said bracket is secured, one relative positioning of the point rail will be obtained, whereas if the bolt l is placed in the bolt holes 3 the point rail will be positioned nearer the main rail. Similarly, if the bolt is placed in the bolt holes 3 the point rail will be positioned still nearer the main rail. It will be understood that the adjustment just described may be secured in connection with either of the brackets D or both of said brackets, the adjustment being proportionately greater when the adjustment is made in connection with both of the brackets.

By forming the brackets with U-shaped jaws we make it possible to use a plain tie bar arranged in the jaws, and provide bolt bearings in each bracket above and below the tie bar wherever the adjustable bolt 4 is located.

We claim:

The combination with switch point rails and a tie bar having a bolt hole therein, of an adjustment bracket secured to one of said point rails, said bracket having a horizontal U-shaped jaw, the upper and lower members of which contain a series of alined bolt holes inclined to a line extendinglongitudiany of the alined holes of said U -shapedjaw, said bolt being adapted to join said parts by extending at all times through the same bolt hole in said tie bar, thereby acif,

quiring adjustment with slight weakening of the tie bar. 7

In testimony that we-claim the foregoing 10 We hereunto afiix our signatures.
